These are the older molds, with the newer recently released molds being squarish and more stylized to reflect the cartoon look.
I am assuming these are just a bunch of older stock figures that they let discounters have.
I personally like the newer style better, but these are pretty good too... I have yet to pick up the newer ones.

Just curious but has anyone else encountered this where bubble isn't adhered to card very well. Found about 4-5 sets of them today and there were quite a few where the bubble was ready to come off card.

Same thing is happening to my Donnie, which sucks as I bought a set with the intention of keeping them mint and to hang on the wall.
